FAN.

- .srnorrrcarron forming part of Letters Patent No. 691,426, dated January 21, i902.

Application filed October 30, 1900. Serial No. 34,885. (No model.)

. tachments; and the principal object of said invention is to cause a better distribution and diffusion of the air-currents than can be obtained by the action of only the moving vanes or wings of the fan.

My invention consists generally in providing the fan with a movable support and connecting with said support one or more movable Vanes or blades against which the currents of air supplied by the fan strike,vand thereby cause the fan-support and fan to move, and also providing means for automatically changing the plane of said vane or` vanes, whereby the currents of air will reverse the movement of the fan-support and fan, so that the currents of air will be moved in different directions.

My invention also consists in certain features and devices herein described.

In the accompanying drawings I have shown one embodiment of my invention, in which- Figure 1 is a side elevation of an ordinary rotary fan with my improvements applied thereto. Fig. 2 is a front elevation of the apparatus constituting the different parts of my invention and with the fan and its support or motor removed. Fig. 3 is a plan view of the same. Fig. et is a detail in longitudinal section of the ball-bearing hanging for the supporting-frame.

Similar numbers represent like parts in all the figures.

1 isan ordinary rota-ry fan consisting of the central hub 2 and the vanes 3. Said hub 2 is secured to the rotary shaft 4, journaled in the casing 5, which serves as the support for the fan 1 and incloses a motor for revolving said shaft and fan.y

6 is the base forsustaining the entire apparatus, including my improvements.

7 is a standard secured to the base 6 and having an arm or bracket 3 extending over said base.

9 is a frame secured to the lower portion of the'casing or support 5 and suspended by a ball-bearing device 10 from the bracket 8. The fan-support 5, with the fan l and its connected parts, is thus suspended from the bracket 8 in a manner to permit its free rotation. I have shown in the drawings a very simple form of the frame 9, which consists of two legs 11 1l, united at the pivotal bearing 10, spreading outward and backward and termiuating in the two feet 12 12, which extend under the support 5, their forward or toe ends 13 being secured to the front portion of said casing. The bend of the feet 12, with the legs 1l, extend around the rear of the bottom of the support 5, and the upwardly-extending toe 13 of each of said feet passes through a lug- 14 on said support.

15 is a cross bar or brace connecting the two feet 12 under the upper pivotal bearing 10, and 16 is a pin extending upward from the base 6 and passing loosely through a hole in the bar 15. This pin 16 is preferably opposite and directly under the center of the pivotal bearing 10, and said pin acts not only as a center of rotation for the fan-casing 1 and the fan, but also as a means to prevent lateral movement of the same, which might strain the pivotal connection l0.

1'7 is a wire guard secured to the support 5 and surrounding the fan 1 for preventing lcontact with the fan from outside objects.

cra or pivots by a rigid tie 21, so that the sur.

faces of said blades will be parallel to each other. This tic 21 is provided with projecting portions or hooks 22 beyond the blades, which hooks or projections overlap a part or parts of the guard, so that the longitudinal movement of the tie 21 is limited in both directions by the hooks coming in contact with the guard 17. This construction will thus limit the pivotal movement in both directions of the blades 18 19, as it is important that the blades should be prevented from turning far enough to get in the same plane, and the position of the hooks 22 is such that they will stop the movement before the blades can acquire such a position. Extending downward from the blade 18 and below the tie 20 is an arm 23, having a horizontal extension 24:. .Iournaled loosely on a vertical bearing on the extension 24 is a wheel 25,

` having preferably a rim of rubber or other yielding material. The parts 23, 21, and 25 serve as means for turning the blade 18 (and through the tie 21) the blades 19 on their pivots when any of said parts meet with an obstruction during the rotation of the fansupport. The loosely-journaled roller 25 provides means for a sufficient yielding of the parts when the rim of said wheel strikes said obstruction, and thus prevents the apparatus from being jarred and injured during its operation.

26 26 aretwo arms pivoted to the pin 16 under the brace 15 and provided with holes near their free ends through which headed pins 27 pass. Between the pins 27 and the pivot 16 the arms are provided with upwardly-projecting pins 28, said pins being directly in the course of the wheel 25 in the rotationof the apparatus.

29 is a plate situated under the arms 26 and provided with holes 30, circumferentially arranged with relation to the pivot 16 as a center and having the same radius as the distance between said pivot and the pins 27. This construction permits the arms 26 to be turned on the pivot 16 in either direction and locked wherever desired, the heads of the pins 27 serving as a means to turn the arms, and the shank of said pins serving as a locking and releasing means by dropping them into and lifting them ont of said holes. In the drawings I have shown the plate 29 made in the form of a ring as being the form that Will require very little material, it being only necessary to have sufficient of a plate in which to have the holes 30.

The pivotal bearing 10 for the frame 9 is constructed as follows:

31 is a screw-bolt passingloosely through a vertical hole in the bracket 8 and adjustably secured to said bracket, from which it is suspended by a nut 32, screwed to said bolt above the bracket.

33 and 34 are bushings screwed to the bolt 31 and provided with annular recesses 35, protected by overhanging flanges or walls 36. These bushing 33 and 34 are so attached to the bolt 31 that their recesses 35 face each other.

37 is a sleeve loosely surroundingthe bolt 31 and having its opposite ends loosely entering the recesses 36 of the two bushings 33 and 34, so as to permit said vsleeve to freely turn on said bolt and bushings. The sleeve 37 is lprovided with two annular shoulders 38, be-

tween which and the inner ends of the bushings 33 34 a series of balls 39 are inclosed. This construction forms an excellent ballbearing for the sleeve 37, which is fixed to the frame 9, so that said frame will be permitted a perfectly free revolution on its suspended bearing 10.

40 is a nut screwed to the end of the bolt 3l below the bushing 34 to hold said bushing in place.

The operation is as follows: The arms 26 are first adjusted by the pins 27, so that the distance between the pins 28 will be the limit of the rotary movement of the apparatus in both directions. The motor is then put into operation, causing the vanes 3 of the fan to rotate on its shaft 4. The current of air caused by such revolution of the fanrwill strike against one side (say the right) of each of the blades 18 and 19, driving said blades and the entire apparatus in the opposite direction, (to the left.) Asthe apparatus can move only on a pivot it turns in the direction in which it is forced. The turning of the apparatus will continue in one direction until the roller 25`strikes one of the pins or projections 28 and cause the blades 18 19 to turn on their pivots, and thus present their opposite sides, (those that have not just been acted on',) to the current of air from the fan. rent will then strike against said sides of the blades and force them and the entire apparatus to turn in the opposite direction to that it held before and until the roller 25 strikes a pin 28, when the blades will be turned again and the operation will be repeated.

From the above it Will be seen that the entire apparatus can be made to automatically andl continuously rotate back and forth in an arc of any desired length, the current from the fan being carried or swept around by such rotation and deflected from the sides of the blades to which the air strikes, thereby causing such current to move radially through the entire arc of its course and enabling an entire compartment or any part of a compartment to be swept by such current of air. The area to be swept by the currents of air may be increased or diminished at pleasure by lengthening or shortening the arc of its movement by means of the adjustable arms 26.
